BEAM-CLAMP.

To all whom it may concern:

Be itknown that I, OTTo Gr. PAINTER, a citizen of the United States,resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented a new and useful Improvement in Beam-Clamps,of which thefollowing is a specification, the principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle, so as to-distinguish it from other inventions.

My invention relates to beam-clamps such as are used for engagingthebases of ordinary I-beams, through the medium of which a hanger may besecured to such beam for the purpose of supporting any desired object,as for instance,-a line of pipe.

The object of theinvention is to provide a beam-clamp which will beeconomical of manufacture, simple of adjustment and effioient in itsoperation.

The said invention consists of means here inafter fully described andparticularly set forth in the claims.

The annexed drawings and the followin description set forth in detailcertain means embodying my invention, the disclosed means, however,constituting but one of various mechanical forms in which the principleof the invention may be applied.

In said annexed drawings: Figure 1 represents a front elevation of abeam-clamp embodying my invention, showing a fragmentary portion of thedepending hanger, and a cross-section of a fragmentary portion of anI-beam, the members of the clamp being shown in their expanded positionprior to adjustment to the beam. Fig. 2

represents the parts shown in Fig. 1 showing same adjusted to andengaging the beam base. Fig. 3 represents a side elevation of the beamclamp, the depending hanger and a cross-section of pipe, together with aside elevation of a fragmentary portion of a beam. Fig. 4 represents afront elevation of the parts shown in Fig. 3 showing the members of theclamp in a modified position.

Fig. 5 is a view similar to that of Fig. 1 showing a modified form ofclamp. Fig. 6 represents a side elevation of the modified form of clampand depending hanger of a fragmentary portion of the pipe shown, as wellas a cross-section of the fragmentary portion of the beam. Fig. 7represents a Specification of Letters Patent.

with reference to each other.

Application filed December 21, 1914. Serial No. 878,416.

vertical section taken upon the plane indicated by line VIIVII in Fig. 6and Fig. 8 represents a similar section taken upon the plane indicatedby line VIII-VIII in said figure.

Theillustrated embodiment of my invention includes two members 1, 1,which are exactly similar in form and construction. One end of each ofthese members is formed with a hook 2 in the usual manner whereby suchend may be caused to engage one side of the base 3 of an I-beam T. Themain or body portion 5 of each such member extends substantiallyparallel with the base of the I- beam when its hook is engaging same asabove described, and as illustrated in Fig. 2. This body portion isformed with a longitudinally extending slot 6 which extends through eachportion and which is bounded at the top and bottom by two serrated sur-'faces 7, 7 respectively, these surfaces forming alternating teeth andspaces. These surfaces are so formed that the teeth formed by onesurface will be disposed opposite to the spaces of the other surfaces,as clearly-shown in Fig. 1. These two members when in their operativeposition are placed so that the body portions are in juxtaposition tothe slots 6 in apposition to each other, the hook portions being atopposite ends of the combined structure thus formed. Extending throughthe slots is a shank 8 of a bolt 9 and this bolt therefore through themedium of the nut 10 may be used to clamp the two members securelytogether and prevent'their longitudinal movement The hanger 11 isprovided in the usual manner with a plurality of holes 12, through theupper one of which passes the shank of the bolt 9.

In applying the above-described structure, the parts are firstassembled, the nut 10, however, being unscrewed so as to permit theparts to be loosely connected. In'

the upper teeth of the one member will be opposite the lower teeth ofthe other member, as shown in Fig. 4:. This forms a rectangular. space13 which is almost completely inclosed and through 'which the shank 8 ofthe bolt extends. The width of the slot and the diameterv of the shankare such that the uninclosed portion of these spaces are narrower thanthe diameter of the bolt shank, so that the latter, therefore, can movelaterally from such spaces, as will be apparent from an inspection ofFig. 2. This construction, therefore, is such that the bolt,

after the parts have been tightened up, and hence the hanger, cannot bedisplaced in a direction longitudinal with respect to the clamp. I

It sometimes occurs that'the continued application of the Weight carriedby the hanger 'will cause the beam-clamp to sag at the center, as shownin Fig. t. When this action occurs, it will be noted that the space 13still further contracts and still more securely locks the bolt againstsuch described displacement. In the modified form shown in Fig. 5, 1have provided the outer ends of each of said clamps the body portions ofwith a protuberance 1 such protuberances being preferably formed bypartially punching the metal. out of the said body portion,

by means of a suitable punch and die. These protuberances are of adiametersuch thatthey may enter the slots and are placed on similarsides of, these body portions so that when the latter are placed intheir assembled position, the said protuberances will project from theinterior or opposed surfaces of the body portions in said slots, asshown. These protuberances therefore prevent the saggingof the twofmembers as illustrated in Fig. 4 and maintain" a substantialparallelism of the said two members to'each other.

Inasmuch as I-beams are of a standard size and the bases thereof aretherefore of in place, without dropping or losing any of them during theoperation, the result of all of which is a considerable saving of timein the application of the clamp to the beam,
